Can Rabbits Eat Green Onions?

Written by: Gemmali Dizor

A balanced diet is key for keeping your rabbit happy and healthy, so you may be wondering if adding green onions to their meals is safe. In this article, we’ll review rabbit diets and determine whether green onions are suitable for consumption by rabbits.

Understanding Rabbit Diets

Rabbits have specific dietary needs that must be met in order to maintain their wellbeing. These include:

Hay and Its Benefits

Hay should make up about 70% of a rabbit’s diet. This provides essential fiber that aids digestion and keeps teeth in top condition. Timothy hay or orchard grass are two popular types of hay recommended for rabbits.

Fresh Vegetables and Fruits

Rabbits can benefit from a variety of fresh vegetables and fruits; however, these should be given in moderation as too much may lead to digestive issues. Fruits should also be given sparingly due to their high sugar content.

Commercial Rabbit Pellets

Pellets offer essential vitamins and minerals for rabbits. However, they should only be given in limited amounts as they tend to be high in calories and could lead to obesity if fed too frequently.

Treats and Occasional Foods

Treats and occasional foods should form a small portion of a rabbit’s diet. These could include small amounts of fruits, vegetables, or herbs not typically included in their daily meals.

Green Onions and Rabbits

Green onions (also known as scallions) are low in calories and packed with essential vitamins and minerals. They boast vitamins A, C, K as well as potassium and folate; however they may not be suitable for certain animal species such as rabbits.

Potential Dangers of Feeding Green Onions to Rabbits

Digestive Issues

Rabbits have sensitive digestive systems, and green onions may cause gas or bloating which could lead to gastrointestinal stasis – a potentially life-threatening condition in which the rabbit’s digestion slows or stops completely.

Toxic Compounds

Green onions contain thiosulfate, which is toxic to rabbits. Consuming green onions may lead to hemolytic anemia–a condition in which red blood cells break down faster than they can be replaced–or lead to death from toxic exposure.

Safe Alternatives to Green Onions

In place of green onions, offer your rabbit a variety of safe vegetables such as:

  • Bell peppers
  • Broccoli
  • Carrots (in moderation due to high sugar content)
  • Cucumber
  • Zucchini

These vegetables offer essential nutrients and can be an ideal addition to your rabbit’s diet.

Herbs and Leafy Greens

Herbs and leafy greens make great treats for rabbits. You can offer them daily in addition to hay or pellets; some examples include:

  • Basil
  • Cilantro
  • Dill
  • Mint
  • Parsley
  • Romaine lettuce
  • Spinach (in moderation due to high oxalate content)
  • Swiss chard
  • Watercress

These herbs and leafy greens offer your rabbit an array of flavors and textures while providing essential nutrients in their diet.


Green onions are not suitable food for rabbits due to their potential digestive issues and toxic compounds. Instead, focus on providing a well-rounded diet with hay, pellets, vegetables, herbs, and leafy greens that your rabbit can safely eat. Always consult with your veterinarian if you have any queries or doubts regarding what your rabbit should eat.


Can rabbits eat other types of onions?

No, rabbits should not consume any type of onion – red, white or yellow – as they contain the same toxic compounds found in green onions.

How Much Fresh Produce Should I Feed My Rabbit Daily?

As a general guideline, provide your rabbit with at least 1 cup of fresh vegetables per 4 pounds of body weight daily. However, this may differ depending on individual needs so it’s best to consult your veterinarian beforehand.

How can I tell if my rabbit has developed gastrointestinal stasis?

Signs of gastrointestinal stasis in rabbits include a lack of appetite, reduced faecal output, lethargy and abdominal discomfort. If you suspect your rabbit is suffering from this condition, contact your veterinarian right away for further evaluation.

Can rabbits eat chives or garlic?

No, rabbits should not consume chives or garlic since they belong to the same family as onions and contain similar toxic compounds.

How Often Should I Offer Fruits to My Rabbit?

Fruits should be consumed sparingly, as they contain high levels of sugar. As a general guideline, limit fruit intake to no more than 1-2 tablespoons per 5 pounds of body weight per week.
